Mapeando la ciudad a través del Bigdata. Análisis temporal de las dinámicas urbanas

Abstract

The relationship between social behaviour and the form of the city, understood not only from a morphological point of view, but also from a functional one, has been extensively studied in the literature. However, in general, this relationship has been analysed on a sectoral basis, in very specific areas such as mobility, touristification or commercial dynamics. In recent years, these studies have evolved due to the availability of data from the digitalisation of systems or social networks that allow a more real and massive approach to people’s behaviour. In this sense, geo-referenced mass data constitute an opportunity to study urban phenomena and map the dynamics generated in cities. In this context, the DINUR project, Method of analysis of urban dynamics through Big(Geo)Data for the regeneration and transformation of the city, funded by the Provincial Council of Gipuzkoa, has been developed with the aim of developing a method for the integration, visualisation and exploratory analysis of heterogeneous and large-scale urban social data that facilitates the understanding of urban dynamics on a municipal scale. It has been applied to the case study of Donostia-San Sebastián. Once the 3 working blocks had been established (space, landmarks and flows), the substantial part of the project consisted of analysing the sources and validating the available information. Based on this, the indicators and the calculation and visualisation method for each case were defined. The application in the case of Donostia-San Sebastián has allowed a spatio-temporal approximation of the use that people make of the city and a sequential analysis of the urban dynamics for each work block. This communication shows the results obtained in the visualization of the same and the most relevant contributions of the research where urban mapping transcends the geographical and makes a leap to the social through the interactions of people, recontextualizing the city.
